Head Movements in Three-Dimensional Localization

Previous studies give contradicting evidence as to the importance of head movements in localization. In this study head movements were shown to increase localization response accuracy in elevation and azimuth. For elevation, it was found that head movement improved localization accuracy in some cases and that when pinna cues were impeded the significance of head movement cues was increased. For azimuth localization, head movement reduced front-back confusions. There was also evidence that head movement can be used to enhance static cues for azimuth localization. Finally, it appears that head movement can increase the accuracy of listeners’ responses by enabling an interaction between auditory and visual cues.
